Title: Ophthalmic compositions for soft contact lens, method of enhancing wettability of soft contact lens, and method of inhibiting terpenoid adsorption
Inventor: DOI KOJI
IPC: A61P31/04
Filed: 1998-08-24
Abstract: An ophthalmic composition for soft contact lenses (SCLs) which contains a terpenoid as the active ingredient; another ophthalmic composition for SCLs which further contains a polyoxyethylene sorbitan ester; a method of enhancing the wettability of SCLs which comprises bringing a terpenoid into contact with the SCLs; and a method of inhibiting terpenoid adsorption onto SCLs which comprises incorporating a polyoxyethylene sorbitan ester into an ophthalmic composition containing a terpenoid. The ophthalmic composition containing a terpenoid functions, for example, to improve the wettability of SCLs and thus inhibit the water content of the SCLs from decreasing. It is hence effective in inhibiting a dry feeling or an incomfortable feeling during SCL wearing. It is thus useful for enhancing the wettability of SCLs. By incorporating a polyoxyethylene sorbitan ester, the terpenoid is inhibited from being adsorbed onto SCLs.

Inventor: FRANKLIN KENT A
IPC: G01H9/00
Filed: 2000-03-29
Abstract: A method and system for directly measuring and controlling the amplitude of an ultrasonic horn comprising an ultrasonic horn; non-contact measurement device for directly measuring an amplitude of the ultrasonic horn, and a controller for modulating the amplitude of the ultrasonic horn in communication with the non-contact measurement device. In accordance with one embodiment, the non-contact measurement device is an optical system in which a high intensity light beam is transmitted from a light source onto a surface of the ultrasonic horn, generating a plurality of reflected light beams. A portion of the plurality of reflected light beams is passed through a lens, forming a light spot which is projected onto a detector. The detector produces an output signal proportional to the strength of the light spot and the location of the light spot on the detector.  Displacement of the light spot on the detector is then determined, which displacement corresponds to the amplitude of the ultrasonic horn. The output of the displacement determination is then input to a controller for controlling the amplitude of the ultrasonic horn.

Title: Online database mining
Inventor: YU PHILIP SHI-LUNG
IPC: G06F17/30
Filed: 1998-09-29
Abstract: A computer method is provided of online mining of quantitative association rules which has two stages, a preprocessing stage followed by an online rule generation stage. The required computational effort is reduced by the preprocessing stage, defined by preprocessing data to organize the relationships between antecedent attributes to create a hierarchically arranged multidimensional indexing structure. The resulting structure facilitates the performance of the second stage, online processing, which involves the generation of quantitative association rules. The second stage, online rule generation, utilizes the multidimensional index structure created by the preprocessing stage by first finding the areas in the data which correspond to the rules and then uses a merging step to create a merged tree in order to carefully combine interesting regions in order to give a hierarchical representation of the rule set. The merged tree is then used in order to actually generate the rules.

Abstract: A method, system, and computer program product for enabling messaging systems to use alternative message delivery mechanisms. In existing instant messaging systems, messages cannot be delivered to an intended recipient unless the recipient is currently logged on to an instant messaging system. According to the present invention, users may register one or more alternative message delivery mechanisms (such as pagers, cell phones, etc.) through which they are available as an alternative to an instant messaging system. Constraints may optionally be added to these registered alternatives, such as specifying a limitation on days of the week and/or hours of the day when a particular alternative may be used. Providing that an alternative messaging mechanism is registered, and any constraints for this alternative are satisfied, in the first preferred embodiment the extended IMS will select a suitable alternative and deliver the message. In a second and third preferred embodiment, the sender of the "instant" message will be informed of the available alternative(s). The sender may then choose to have his message delivered even though the intended receiver is not currently logged on to an instant messaging system. Fourth and fifth embodiments enable a message to be delivered to a recipient using a registered mechanism (that may include an IMS), and provide for determining availability of a selected user. Using these techniques, the real-time awareness of potential message receivers in instant messaging systems is extended.

Title: Method and system for internet production and delivery of legal documents
Inventor: HICKEN MARK P
IPC: G06Q50/18
Filed: 2000-06-22
Abstract: The traditional way for a client to obtain a legal document is for the client to contact a lawyer often through referral or advertising. This method of obtaining legal documents is inappropriate in cases where the client wants a simple legal document which does not require a great deal of consultation time or where the client simply wants an assessment of the costs involved.  From the lawyer's perspective, it is inefficient because the method of gathering the information is labour-intensive and time is wasted interpreting the client's legal needs in cases where the client may elect not to proceed. The present invention provides a method for producing and delivering legal documents over the Internet while maintaining solicitor/client privilege, by providing a web site linked to lawyers by legal practice area and jurisdiction, who receive and reply to client document requests through the web site.

Patent CA-2334295-A1 (CA)
Title: Air bubble sensor
Inventor: COLE MARTIN A
IPC: A61M5/00
Filed: 1999-06-04
Abstract: A system and a method for detecting the presence of air bubbles in an intravenous (IV) line supplying a medicinal liquid to a patient. An air bubble sensor includes an ultrasonic transmitter acoustically coupled to an ultrasonic receiver to detect the presence of a gas (e.g., air) in a portion of a tube comprising the IV line. The transmitter and receiver are mounted on pivoting transducers that are disposed on opposite sides of the tube. A spring biases the transducers inwardly to-ward each other so that the transmitter and receiver contact opposite sides of the tubing. This assembly automatically accommodates different sizes of tubing and tubing of a relatively wide range of stiffness. The tube is connected to a disposable pumping cassette that is engaged in a pump chassis on which the transducers are pivotally mounted. A user actuated plunger on the pump chassis is depressed to cause the transmitter and receiver to move away from the tube when the pumping cassette is removed from or inserted into the interior of the pump chassis. A controller precisely monitors the flow of medicinal liquid through the tubing to detect the size of gas bubbles and total volume of gas infused. The controller automatically compensates for minor contamination of the exterior surface of the tube, e.g., if the surface is wet with a liquid.

Title: Fuel-fired liquid heating appliance with burner shut-off system
Inventor: LANGMEAD JOHN P
IPC: F23N5/24
Filed: 2001-09-10
Abstract: A fuel-fired heating appliance, representatively a gas-fired water heater, has a combustion chamber in a lower end portion thereof, and fuel burner apparatus having main and pilot burner portions is operatively disposed in the combustion chamber. During operation of the water heater combustion air is supplied to the burner apparatus only via a duct structure having an inlet elevated relative to the floor or other horizontal support surface upon which the water heater rests. A flammable vapor sensor is mounted on the lower end portion of the water heater, externally of the combustion air supply duct structure and at an elevation lower than that of its elevated inlet, and is operatively connected to burner control circuitry which, in turn, is coupled to the burner apparatus.     In the event flammable vapors are generated near the floor adjacent the water heater, the vapor sensor operates to detect such vapors and responsively disables the burner apparatus via the control circuitry. The difference in elevation between the vapor sensor and the elevated combustion air inlet gives the sensor additional time to detect and respond to flammable vapors before they upwardly reach the elevated combustion air inlet.
